STS-94 Commander James D. Halsell, Jr., speaks to the media at the Shuttle Landing Facility after the crew arrived at Kennedy Space Center in preparation for the reflight of the Microgravity Science Laboratory-1 mission. Launch is scheduled for July 1, 1997, at 2:37 p.m. EDT. From left to right, the crew members are Payload Specialists Gregory T. Linteris and Roger K. Crouch; Mission Specialists Michael L. Gernhardt and Donald A. Thomas; Payload Commander Janice E. Voss; Pilot Susan Leigh Still and Commander James D. Halsell, Jr. One of the T-38 jets aboard which the crew arrived can be seen in the background. The laboratory was scheduled to fly again with the full complement of STS-83 experiments after that mission was cut short due to a faulty fuel cell. During the scheduled 16-day STS-94 mission, the experiments will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducts combustion, protein crystal growth and materials processing experiments.
